Swift Package Index • GitHub • API Alerts

Effortless project notifications. Send once, deliver everywhere.

Installation

Add the package in Xcode via File → Add Package Dependencies:

https://github.com/apialerts/apialerts-swift

Or in Package.swift, add the package to dependencies and the product to your target:

dependencies: [
    .package(url: "https://github.com/apialerts/apialerts-swift", exact: "1.2.0")
],
targets: [
    .target(
        name: "YourTarget",
        dependencies: [
            .product(name: "APIAlerts", package: "apialerts-swift")
        ]
    )
]

We recommend pinning to an exact version.

Quick Start

import APIAlerts

APIAlerts.configure("your-api-key")
APIAlerts.send(Event(message: "Deploy complete"))

Usage

Global singleton

Call configure once at startup, then use send / sendAsync anywhere.

import APIAlerts

APIAlerts.configure("your-api-key")

// Fire-and-forget. Never throws, drops errors silently unless debug is on.
APIAlerts.send(Event(message: "Deploy complete"))

// Or get the result back. Never throws; switch on the Result.
let result = await APIAlerts.sendAsync(Event(message: "Deploy complete"))
switch result {
case .success(let sent):
    print("Sent to \(sent.workspace ?? "") (\(sent.channel ?? ""))")
case .failure(let error):
    print("Error: \(error.localizedDescription)")
}

Enable debug logging

APIAlerts.configure("your-api-key", debug: true)

Critical errors (missing API key, not yet configured) always log. Success and warning messages only log when debug is enabled.

Event fields

Only message is required. All other fields are optional and omitted from the request body when nil.

let event = Event(
    message: "Deploy complete",
    channel: "releases",
    event: "ci.deploy",
    title: "Deployed",
    tags: ["CI/CD", "Swift"],
    link: "https://github.com/apialerts/apialerts-swift/actions",
    data: ["commit": "a1b2c3d", "branch": "main"]
)

APIAlerts.send(event)

data takes anything Encodable (a dictionary as above, or your own Codable struct) and is available to non-push destinations for templating.

Field	Type	Required	Description
`message`	`String`	Yes	Human-readable notification text. This is what appears on the push notification lock screen.
`channel`	`String?`	No	Workspace channel the push notification fires on. Defaults to the workspace default channel when omitted.
`event`	`String?`	No	Identifies what kind of thing happened. Optional but recommended. Use dotted notation (e.g. `ci.deploy.success`, `payment.failed`, `user.signup`) so routing rules can match glob patterns like `ci.` or `.failed`.
`title`	`String?`	No	Short headline some destinations render separately from the message body.
`tags`	`[String]?`	No	Categorisation tags for filtering and search.
`link`	`String?`	No	URL associated with the event. Available as a deeplink for push notifications and as a call-to-action for routed destinations.
`data`	`(any Encodable & Sendable)?`	No	Arbitrary key-value metadata. Available to non-push destinations for templating (Slack message bodies, email templates, webhook payloads).

Send to multiple workspaces

Pass an apiKey as the optional last argument to override the configured key for a single call.

APIAlerts.send(Event(message: "Deploy complete"), apiKey: "other-workspace-api-key")

let result = await APIAlerts.sendAsync(
    Event(message: "Deploy complete"),
    apiKey: "other-workspace-api-key"
)

Dependency injection

The singleton is fine for most apps. When you want injection, mocking, or multiple keys in one process, construct an ApiAlertsClient directly. It conforms to ApiAlertsClientProtocol, so hold the protocol type in your code and swap a stub in tests. The singleton is a thin facade over a default ApiAlertsClient, so both share the same behaviour.

import APIAlerts

struct DeployNotifier {
    let alerts: any ApiAlertsClientProtocol

    func notify() {
        alerts.send(Event(message: "Deploy complete"))
    }
}

// Production
let notifier = DeployNotifier(alerts: ApiAlertsClient("your-api-key"))

In tests, inject any type conforming to ApiAlertsClientProtocol. To test against the real client, inject a URLSession (e.g. one backed by a mock URLProtocol):

let client = ApiAlertsClient("your-api-key", debug: true, session: mockSession)

API

Method	Description
`APIAlerts.configure(_:debug:session:)`	Initialise the singleton. First call wins; subsequent calls are no-ops.
`APIAlerts.send(_:apiKey:)`	Fire-and-forget. Synchronous, returns immediately; delivery runs in a detached task. Never throws, drops errors silently unless `debug` is on.
`APIAlerts.sendAsync(_:apiKey:)`	Awaitable, returns `Result<SendResult, ApiAlertsError>`. Never throws.
`ApiAlertsClient(_:debug:session:)`	Constructable instance client for dependency injection. Conforms to `ApiAlertsClientProtocol`; exposes the same `send` / `sendAsync` / `setOverrides`.

SendResult fields

Field	Type	Description
`workspace`	`String?`	Workspace name (present on success)
`channel`	`String?`	Channel name (present on success)
`warnings`	`[String]`	Non-fatal warnings from the server

Errors are surfaced via the Result's .failure(ApiAlertsError) case, not as fields on SendResult.
